Banshee doesn't start

[DanH]

Banshee refuses to start. This is probably because I don't have enough gstreamer-0.8 installed (see output below) - and banshee doesn't require enough of it even to produce a meaningful error message when run.

Here's what banshee says:

$ banshee

Try installing gstreamer0.8-misc... this should fix it :)
I won't fix the package for now as we'll switch to gstreamer 0.10 with the next upload

[DanH (holmsand-gmail)]

Thanks, now it seems to use gstreamer 0.10. But it still doesn't start, though. Now it says:

Warning: [3/7/2006 9:07:34 AM] (Cannot connect to NetworkManager) - An available, working network connection will be assumed

ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/gstreamer-0.10/libgstvideobox.so

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

[Sebastian Dröge (slomo)]

Do you have some packages installed from source on your system? For example some gstreamer 0.10 stuff? #33508 seems to be like the same error and was fixed by removing everything not installed from the dapper gstreamer packages...

[Joakim (jryden)]

I don't, and I have the same issue. Though for me it started whining about loading libgstresamplerate.so or sumsuch. Just for kicks I moved that out of the way and it just complained about another .so file instead.

[Sebastian Dröge (slomo)]

Could you try the following?

gdb --args mono /usr/lib/banshee/banshee.exe
handle SIGXCPU SIG33 SIGPWR nostop noprint
run
[wait for the segfault]
backtrace

then run 'p mono_print_method_from_ip ($address)' on every address that is not 0x00000000 and not resolved to some symbol. Copy everything in here or better attach it as an text file because that's easier to read ;)

[Joakim (jryden)]

These are the ones that gave any output other than "than no method at..."

[Sebastian Dröge (slomo)]

Could you please also paste/attach the backtrace?

[Joakim (jryden)]

my bad :)

[Sebastian Dröge (slomo)]

Thanks... what type of CPU do you have?

[Joakim (jryden)]

x86 (p4)

[Sebastian Dröge (slomo)]

interesting... this happens for someone else on a p4 and p-m too, but it works fine on athlon xps... maybe the SSE2 optimizations in liboil are a bit too aggressive ;)

[DanH (holmsand-gmail)]

Sebastian: no I haven't ever installed anything gstreamer-ish from source.

I'm getting a backtrace similar to Joakim's when running under gdb (attached).

[Sebastian Dröge (slomo)]

DanH, what type of CPU do you have? A Pentium 4 too?

[DanH (holmsand-gmail)]

Oh, sorry, I should have told you: Pentium M.

[Germán Poo-Caamaño (gpoo)]

The first error is completely different to the last one. I was a banshee 0.10.6 running fine, until it was upgraded today to bansee 0.10.7. I get exactly the same error.

If I remove (or rename) /usr/lib/gstreamer-0.10/libgstvideobox.so, then I get the error with /usr/lib/gstreamer-0.10/libgstaudioresample.so, and then with /usr/lib/gstreamer-0.10/libgstvideotestsrc.so.

Moving (or deleteing) those three plugins away it works again.

Pentium M.

[Sebastian Dröge (slomo)]

gpoo: sure, that's unrelated to the original bug... it shows up with muine and banshee when using gst 0.10 on pentium4/pentium-m for some reason...

[Brandon Hale (brandon)]

This seems to be an Intel specific bug in liboil.
Reassigning.

If you want a quick work around, install liboil0.3 from Debian Unstable.

[Sebastian Dröge (slomo)]

Can someone who has the problem please install this file and give me another backtrace?
This is a debug build of liboil

[Jonah Bull (jonahbull)]

Just a quick "me too," I guess. I also have a Pentium M and renaming/removing those files (libgstvideobox, libgstaudioresample, and libgstvideotestsrc) "fixes" this problem.

[Sebastian Dröge (slomo)]

ok, i got access to a pentium4... here's a backtrace with a debug build of liboil

[Sebastian Dröge (slomo)]

Ok, it's related to the SSE support in liboil. I'll disable it for now until a better solution is found.

Just for the record, this only happens under certain circumstances, not sure yet which... doing exactly the same as banshee/muine does to initialize gst/liboil (calling gst_init(NULL, NULL) ) in a small testcase doesn't break anything, no matter whether it's done from mono or in a small C program.

[Sebastian Dröge (slomo)]

Should be fixed with 0.3.7-0ubuntu4
Please reopen when you have this problem again
